Hydroxyl-containing ammonium oligomers containing a furan heterocycle were synthesized. Their use as modifiers of properties of rigid polyurethane foams makes it possible to improve technological parameters of molding and physical and mechanical properties of urethane foams. The quaternary ammonium compounds used were found to act as "soft" catalysts, cross-linking agents and flame retardants.

The influence of the CO-4 stabilizer on the rheological properties of polymer composite materials based on UHMWPE has been studied. It has been shown that the addition of a CO-4 stabilizer to polymer matrices significantly affects the rheological properties of materials and their extrudability. There is a change in the conformations of macromolecular chains, the absence of dependence of the viscous component on the relaxation process of the dispersed system, an increase in the complex viscosity, which led to a deterioration in the processability of the material. Based on the Han curves, it is shown that the addition of a CO-4 stabilizer leads to a deterioration in the miscibility of mixtures, i.e., the phase separation of the components of the obtained samples increases.

Polymer composite materials have been developed using polyester-urethane-acrylate resin based on 2,5-furandicarboxylic acid obtained from plant biomass and a number of synthetic (carbon, glass, and aramid fibers) and mineral (basalt) fibrous fillers. The high operational characteristics of the obtained PCMs are demonstrated. The effect of hybridization of synthetic fibers with natural cellulose fibers (cotton) on the physical and mechanical properties of polymer composite materials has been studied. An increase in tensile strength with a simultaneous decrease in the density of PCM using a carbon fi ber/cotton hybrid filler is shown.
